Good evening community,
I am currently trying to make a layout and my code dosen't reflect what it should be.
Here is what it's suppose to look like:
Basically the text blend into the tealish bar
and this is what I have:
What to do?
Your Image is clear but your question is not, in the TextView you have to place the text what ever you want Hardcoded or not.
android:text="Your text here"
but if you want your TextView to show different results, you have to place an ID of TextView and initialize it in your Java code

i want to make a program. I have 16 textviews that includes letters. And i want to add small text to every textview -programmatically-. Please refer to the pictures..
firstly --> picture
after adding --> picture
You may do this:
Instead of getting textviews into the program, you can create a layout file which contains 2 text views. You may need to use "layers" to do this. One for big text, other one for the little text which contains the reduced size texts. Then inflate the layout file to a view by an inflater. Then use that view instead of textview. So you have little numbers on you table now.
I don't know about RecyclerView, may be that can be a better solution but as i said i dont know it so here is my answer, good luck at your project!
<TextView
android:text="123456789"
android:autoLink="phone">
</TextView>
I want to create this TextView from code, however I am encountering countless problems.
In the first place, I got halfway creating a TextView and adding this:
tw_phone.setAutoLinkMask(0x04);
This resulted in a clickable TextView, but when you clicked, a toast said "No application can perform this action", or something similar. I also tried with
Linkify.addLinks(tw_phone, Linkify.PHONE_NUMBERS); //and .ALL
but it gave me the same result.
When I decided to ask on StackOverflow, I tried to strip my code down incase there were something wrong with the way I have used Layouts (you never know), but now I'm not even able to make a TextView clickable. This is the code that, in my opinion, should work as it is just a stripped down version of what I am using deeper in my code.
TableLayout table = (TableLayout) findViewById(R.id.tableResult);
TableRow row = new TableRow(this);
TextView tw = new TextView(this);
tw.setText("123456789");
tw.setAutoLinkMask(Linkify.ALL);
row.addView(tw);
table.addView(row);
Can someone write a simple, small example of how you create a TextView, give it a number as text and then allows the user to click on it and choose whatever app they want to open the number with??
If you can point out whats wrong in my code aswell, that would be great, but I would much rather just get the answer straight away. The things I have tried are taken from other StackOverflow questions and answers.
TextView tv_contatti2 = new TextView(this); tv_contatti2.setText(contatti);
Linkify.addLinks(tv_contatti2, Linkify.PHONE_NUMBERS);
tv_contatti2.setLinksClickable(true);
where "contatti" has value +39012345678 with international prefix
In order to make text view clickable with any url try following code :
Linkify.addLinks(textView, Linkify.WEB_URLS)
I need to implement TextView widget in cocos2d-android-1 and don't know how please help
TextView textView = null;
textView.setText(R.string.billing_not_supported_message);
addChild(textView);
This code not working because addChild needs node. Please help really need.
I completely agree that the android version of cocos2d needs some serious 'standard UI' features adding to it.
At the moment, your only real option is to take a similar approach to my previous answer here
ANDROID:How to open web page in class extends CCLayer
whereby you have a layout which will put a textview on the screen (or you construct it yourself in your handler), and you use a handler from the activity which your scene is running in to show/hide it.
It's clunky and horrible but it works. In my field designer app i faced the same problem, but i also had to have a custom background to the text field, which resized with the text field, that had a rough edge, and the text view had to fall inside that rough edge so all the text was visible on the main bit of the background.
i achieve that using this same technique, but i created a layout xml file so that i had control over how the textview and it's background were displayed.
(note to show/hide the textview i had to give its root layout a constant ID and check for if that ID existed, and was visible, as when people touched outside it, i needed to make it vanish)
I'm fairly new to Android programming and I've got this project I need to finish and I'm currently stuck.
I've got a standard listview in a Menu class with an array containing around 20 different elements. So what I want to do is load images in an imageview depending on which item in the listview I click, and since I'm a beginner the only idea I had was to make a new activity for each imageview which seems like a pretty bad way to do it since I'd need about 20-30 new activities..
To sum things up what I want is:
Code for making ONE activity that will display a different image depending on which item in the listview I click, probably pretty basic coding I want as simple solution as possible.
If possible I'm also looking for a solution that includes an SQLite database that stores the URL of an image and then display it in a single activity, also depending on which item I press in my current listview.
(I hope you understand my needs, and if you need I can also post my current code for the Menu class if it helps you help me) Or you can just show me a different way to make this work, I appreciate every answer! Thanks in advance!
NOTE
And please keep in mind, I'm a noob at Java and Android so keep it rather simple or at least explain what you do.
When you click on a list item, display the image in another view in the same layout, unless you want the image to take up the entire screen real estate. If you want it in the entire screen, go to a new Activity by sending the activity an Intent.
Activities are the "controller" of your application. They interact with the visible UI and the input from the user. You don't need a separate activity for each image, just an activity that's associated with a "place" in the UI (an ImageView) where you'll display the image.
I'd start by adding the images as resources under res/drawable before going on to databases.
You are going to have to do most of this yourself. There really isn't any substitute for taking the time to learn Java and Android. There are several tutorials and Android University classes under the Resources tab in the Developers Guide; I suggest you do all of them.
Basically what I want to do in my Android app is use TextView to display two different pieces of text at once. So in code, I want to be able to do something like this:
LinearLayout ll = new LinearLayout(this);
TextView text = new TextView(this);
text.setTextColor(0xFF000000);
text.setGravity(Gravity.CENTER_HORIZONTAL);
text.setTextSize(20f);
text.setText("Text1");
text.setTextSize(14f);
text.setColor(0xFF0000FF);
text.setText("\nText2");
ll.addView(text);
To clarify, I am trying to display a black "Text1" and a blue "Text2" at once using only a single TextView. Obviously this doesn't work out using the code above. I've considered using a second TextView but that seems like a waste of effort and memory to me. I'm sure the brilliant minds here can come up with the best solution to this.
Thank you very much in advance for your time and your assistance.
There are two options for you.
One is
Spannable
and other is
fromHtml (String source)
So that you can get your desired output.
I think with the current version of the code, you can see only the latest text (Text2).
If you want to have multiple look and feel for two texts, I would suggest use 2 separate TextViews. It would add more flexibility.
If you are not going to change this UI code later, then you can consider Html.toHtml() in setText() call.
It seems the problem is with:
LinearLayout.addView(text);
You are trying to add a view to a LinearLayout, but the layout doesn't exist (in the current activity). You need to add the TextView to a Layout defined in the .xml you are using. Suppose you have a LinearLayout with id "linearlayout01" in the xml file "activity1.xml", you would do something like:
setContentView(R.layout.activity1);
// Create and adjust TextView text
...
LinearLayout layout = (LinearLayout) findViewById(R.id.linearlayout01);
layout.addView(text);
Once a View is added to a ViewGroup of which LinearLayout is a descendant you do not need to readd it to update its display. If you preform any changes on a view that requires it to change its display it will handle all the proper notifications about required redraws or relayouts by calling View#invalidate and View#requestLayout where appropriate.
In addition, because all UI changes are handled on the same thread you do not need to worry about calling multiple methods that will update the UI. This is because of two reasons, first, the execution of the redraws will not occur until your code is finished, second, android has optimizations built in that combines multiple invalidate calls into one.
So, the only thing you need to worry about is getting a proper reference to your TextView instance and then you can call all the methods on it that you need to make it display what you wish.
Since you are creating your Views manually and not from xml you need to add your root ViewGroup to the Activity by calling Activity#setContentView.
Edit:
Then you're going to need to learn about SpannableString and SpannableStringBuilder. There is some very brief documentation here: Selecting, Highlighting, or Styling Portions of Text
when do you plan to update the textview ? If it is on click of a button then get a reference to the textview and in the onClickListener() update the text, color, etc whatever you want to do.
After seeing your other comments, I think SpannableString is what you are looking for
